Expose Daml stacktraces for Daml Script errors (#9025)
* Expose Daml stacktraces for Daml Script errors

This finally plugs together the pieces from the previous PRs to
provide stacktraces on any ScriptF command (and thereby anything
involving an interaction with the ledger).

fixes #8754

changelog_begin

- [Daml Script] When running Daml Script on the command line you will
  now see a Daml stacktrace on failures to interact with the ledger
  which makes it significantly easier to track down which of the calls
  fails. By default, you will only get the callsite of functions like
  `submit`. To extend the stack trace, add `HasCallStack` constraints
  to functions and those will also be included.

Fix closure references in Daml Repl (#8950)
* Fix closure references in Daml Repl

Turns out the comment "we probably need to extend this to merge the
modules from each line" was exactly correct: If the result evaluates
to a closure (or a value including a closure), it can reference
definitions from the current module. This happens if the simplifier
lifted something out of the current definition (otherwise we have only
one and it cannot be recursive so no chance of leaking a reference).

This PR fixes this by checking whether the result references the
current module and if it does, we keep it around.

Disable deriving-defaults per file (#8684)
Disabling it per target works nicely for compilation but it gets
annoying in ghci since the warnings are still triggered. We could
disable it everywhere but I think the warning is generally useful. I
tried patching proto3-suite to use DerivingStrategies but that doesn’t
work because haskell-src is dead and doesn’t support it. So for now
adding it to the per-file list seems like the best option.

Upgrade scalafmt and enable trailing commas (#8437)
This PR updates scalafmt and enables trailingCommas =
multiple. Unfortunately, scalafmt broke the version field which means
we cannot fully preserve the rest of the config. I’ve made some
attempts to stay reasonably close to the original config but couldn’t
find an exact equivalent in a lot of cases. I don’t feel strongly
about any of the settings so happy to change them to something else.

As announced, this will be merged on Saturday to avoid too many conflicts.

Port damlc dependencies to Scala 2.13 (#8423)
* Port damlc dependencies to Scala 2.13

I got a bit fed up by the fact that going directory by directory
didn’t really work since there are two many interdependencies in
tests (e.g., client tests depend on sandbox, sandbox tests depend on
clients, engine tests depend on DARs which depend on damlc, …).

So before attempting to continue with the per-directory process, this
is a bruteforce approach to break a lot of those cycles by porting all
dependencies of damlc which includes client bindings (for DAML Script)
and Sandbox Classic (also for DAML Script).

If this is too annoying to review let me know and I’ll try to split it
up into a few chunks.

Cache computation of top-level values at definition level (#7818)
* Cache computation of top-level values at definition level

Earlier the computation of a top-level value was only cached at the
use-site in SEVal. This introduces SDefinition which contains the same
mechanism as SEVal to cache the computation.

As expected this does not impact performance much:

before: CollectAuthority.bench  //daml-lf/scenario-interpreter/CollectAuthority.dar  CollectAuthority:test  avgt   40  44.267 ± 0.728  ms/op
after: CollectAuthority.bench  //daml-lf/scenario-interpreter/CollectAuthority.dar  CollectAuthority:test  avgt   40  43.693 ± 0.702  ms/op

What this does have a significant impact is on reducing the number of distinct
SValues for things like type class dictionaries etc, so that now we have one
SValue per dictionary rather than one per SEVal.

Fix trace statement handling in DAML Script service (#7292)
* Fix trace statement handling in DAML Script service

This PR makes sure that we get both trace statements coming from the
ledger client as well as from the ledger server. In the script service
those are two different Speedy machines so we need to interleave
them. This is a bit messy so let me explain the steps (apologies for
not splitting it up but I think it’s easier to understand the
motivation when it is a single PR):

1. Abstract over the tracelog interface. The ringbuffer doesn’t makes
   sense for our purposes and is annoying to clear.

2. Pass in the respective fields of `Machine` to `Conversions` instead
   of the whole machine. This is both a simpler design (passing around
   mutable objects scares me) and it allows us to assemble the fields
   from different machines.

3. Initialize the ledger machine with a simple ArrayBuffer tracelog.

4. After `submit` and `submitMustFail` copy the tracelog from the
   ledger to the client.

Windows since `.sh` files are not directly executable on Windows.

This change fixes the issue by producing the script file in a dedicated
rule and then wrapping it in a `sh_test` rule which also works on
Windows.

This extends DAML REPL to behave similar to GHCi in that it prints

pure, non-script expressions now. We copy the same hack from GHCi and
typecheck multiple times. This doesn’t seem to have any noticeable
performance impact (which makes sense, the expressions are tiny and
the overhead of grpc is much much bigger).

Revert ANF changes and add a testcase for evaluation order (#6645)
* Revert ANF changes and add a testcase for evaluation order

After careful consideration, we decided that the change in evaluation
order that was accidentally introduced by the ANF changes should be
considered a breaking change or arguably even a bug and should not
land in 1.3.0.

Therefore, this PR reverts the following commits:

1. 353d0da6f7
2. a45b51042f
3. 04c7b2af7f
4. a624dd7242
5. b3aab72cee

Other PRs mostly had trivial merge conflicts that I resolved. The two
most interesting ones here are probably

1. https://github.com/digital-asset/daml/pull/6576 which was easy to
   resolve and the change to return SEValue instead of SExpr is still
   nice and useful even if we do not need the guarantees.
2. it https://github.com/digital-asset/daml/pull/6542 which required
   some changes since the constructors changed. If you want to review
   those changes in detail (they are pretty straightforward so not too
   important), it’s probably easiest to check out this PR and run
   ```
   git diff 2cd2a8f2a8
   daml-lf/interpreter/src/main/scala/com/digitalasset/daml/lf/speedy/Compiler.scala
   ```
   to see the diff to the parent commit of the first commit that

Speedy ANF (#6440)
* ANF transformation in Speedy.

The idea behind this PR is to transform speedy expressions into a simpler form where all non-atomic sub-expressions are made explicit by the introduction of let-forms. In particular, for the function-application form. These simpler forms allow the execution engine to take advantage of the atomic assumption, and often removes many additional execution steps. In particular the pushing of continuations to allow execution to continue after a compound expression has been reduced to a value.

Support multiple auth tokens in DAML Script (#6473)
* Support multiple auth tokens in DAML Script

This piggy backs on top of the already existing --participant-config
feature. While you can argue that it might be slightly confusing that
you have to specify the same participant twice to specify different
auth tokens, I think this actually makes sense: In an ideal
world (ignoring any performance issues) you have one participant per
party anyway and one connection per participant specified in the
config file still seems like a very reasonable model.

changelog_begin

- [DAML Script] You can now use DAML Script with multiple auth
  tokens. This is particularly useful if you are working with the JSON
  API where you can only have one party per token or with an IAM that
  only provides single-party tokens. The tokens are specified in the
  participant configuration passed via `--participant-config` in a new
  ``access_token`` field. The existing `--acess-token-file` flag is still supported if you want to use the same token for all connections. See
  https://docs.daml.com/daml-script/index.html#running-daml-script-against-authenticated-ledgers
  for more details.

Integrate time service into DAML Script (#6417)
This integrates the time service into DAML script thereby covering the
main piece of scenarios that was missing from DAML script.

This PR does two things (they are very related and doing them together
makes it much easier to test):

1. It “fixes” `getTime` to return the ledger time in static mode by
   querying the ledger time service instead of defaulting to the Unix
   epoch which is pretty useless and I would consider the old behavior
   a bug. We keep the old behavior via the JSON API since there is no
   time service.

2. It adds `setTime` to set the ledger time via the time service. This
   is only supported in static time mode (sadbonx and other ledgers do
   not expose the time service in wallclock mode because changing time
   makes it not wallclock) or via the JSON API (no time service).

fixes #6220

changelog_begin

- [DAML Script] DAML Script’s `getTime` now correctly handles time
  changes in static time mode and returns the current time by querying
  the time service rather than defaulting to the Unix epoch. Note that
  when run via the JSON API, it still returns the Unix epoch.

- [DAML Script] Add `setTime` to DAML Script which sets the ledger
  time via the ledger API time service. Note that this is only
  supported when running over gRPC in static time mode.

Add control to speedy compiler to choose if stack-trace support occurs at runtime. (#6070)
Choices for `stacktracing` are `NoStackTrace` / `FullStackTrace`.

Adapt code so the selection is made by the original caller:
- `engine`
- `scenario-service`
- `repl-service`
- `daml-script` runner
etc

Currently, all callers pass `FullStackTrace` (the existing behaviour), except for the
exploration dev-code: `daml-lf/interpreter/perf/src/main/scala/com/daml/lf/explore`.

The idea is that once this control is in place, we can discuss if we can change how we
might expose it to the user, and/or perhaps change the default behaviour to have
`stacktracing` disabled.

Implement a simple profiler for DAML scenarios (#5957)
* Implement a simple profiler for DAML scenarios

The profiler runs a single scenario and records timing information when
each function (and some other closures) are entered and left. The
resulting information can be visualized as a flamegraph using
[speedscope](https://www.speedscope.app/).

The profiler works by instrumenting the CEK machine at the heart of
DAML Engine. Unfortunetaly, this causes a very small overhead on
non-profiling runs too. However, in my benchmarks I could not measure
any significant impact on the overall runtime at all. More precisely,
the overhead is as follows:

Every closure now has an additional field called `label`. In
non-profiling runs this field is always set to `null`. This field needs
to be allocated, copied whenever we copy a closure and scanned during
garbage collection. Additionally, whenever we enter a closure, we check
this field and whenever it is _not_ `null`, i.e. never during
non-profiling runs, we record an "open event" and set up a hook for the
corresponding "close event". Thus, the additional cost during
non-profiling runs are a single pointer comparison and a jump beyond
the "then branch".

Since this is still very much in active development, there are no
documentation, other than an entry in a README, and no tests yet. They
will come before we promote this. However, the UX will look very
different then since we already have plans to significantly change it.

Make max-inbound-message-size in DAML script/repl configurable (#5996)
Fixes #5592

The CLI syntax and the defaults follow the JSON API here.

changelog_begin

- [DAML Script] The maximum inbound message size can now be configured
using `--max-inbound-message-size``. This matches the flag in the JSON
API.

- [DAML REPL] The maximum inbound message size can now be configured
using `--max-inbound-message-size``. This matches the flag in the JSON API.

Improve error messages in daml repl on calls to error (#5565)
* Improve error messages in daml repl on calls to `error`

There were two issues with calls to `error`:

1. This one is harmless but somewhat annoying: When calling `error` we
   run into the log statement in `stepToValue` which prints out the
   error message in a fairly reasonable form (you can argue whether
   Error: User abort: is a super useful prefix but that’s a relatively
   minor issue). Afterwards we then call `println` on the failed
   future. However, that will just print the type of the exception
   which isn’t something we want to show to users. I’ve just disabled
   the println statement if the exception is `SError`.

2. This one is a bigger issue: `throw x` is not the same as
   `Future.failed(x)`. I only fully realized the difference fairly
   recently. The former fails before it produces a future. So `(throw
   x).onComplete(…)` will never execute the callback. The latter is
   just a failed future. It is rather confusing to have a function
   that returns a future but then throws an exception instead of a
   future and it confuses the grpc library which prints out a horrible
   exception. I’ve changed all calls to `throw` in `runWithClients` to
   instead use `Future.failed` and `flatMap` (in the form of
   for-comprehensions).
   There are still a few calls in `run` left which I’ll leave for a
   separate PR.

I think we need to factor out some helper functions here to make this
a bit more manageable (e.g. for the Converter.toFuture) stuff but I’ll
leave that for a separate PR. You probably want to view this with
whitespace diffs disabled.

Split up repl tests to make them faster (#5450)
* Split up repl tests to make them faster

This PR splits up the tests into the tests for TLS and Auth and the
tests for the actual functionality.

The func tests use the repl as a library which allows them to be
significantly faster:

1. We only need to start the service process once.
2. We only need to initialize the package db once.

There is at least one other point that I did not address for now and
that is only loading the packages into the repl service once. While
loading them multiple times is a noop, it still has a performance
implication.

Sadly, this has turned out much more messy than I thought it would be
due to various issues with haskeline/repline/tasty/computers. The
details are in a comment in DA.Test.Repl.FuncTests.
